CVE-2026-14230: Unknown Ecs

Medium severity, CVSS 5.4. EPSS: 0.2% chance of exploitation in the next 30 days.

The ECS WordPress plugin before 4.3.8 does not perform capability or object-ownership checks on its Dynamic Repeater AJAX handlers (gated only by a capability-agnostic nonce that any edit_posts user obtains from the Elementor editor), so a Contributor can write a data-source binding into any post — including admin-authored pages — whose attacker-controlled values are rendered into a widget's repeater output without sanitization, executing JavaScript in the session of any visitor or administrator who views the page.

Affected products

• Unknown Ecs: before 4.3.8 (fixed in 4.3.8)
